Add Bazel feature flags functionality

This allows Tulsi to define flags conditional on Swift/non-Swift,
certain project configurations, etc. without impacting the Bazel
analysis cache.

Previously we would directly set Build Settings on the generated
xcodeproj in order to pass down these flags; however, this is
not a valid solution for caching reasons.
